Windows 10: Windows 10 "Choose where to get apps" is grayed out.

I just got a scanner, the Epson v600, and it comes with an install package, direct from Epson. When I try to install it, though, windows tells me "The app you're trying to install isn't a Microsoft-verified app" and wants me to go to the App store to get some other app. It also gives me a link to "Change my app recommendation settings". When I click that, I am presented with the "Apps & Features" screen with an option for "Choose where to get apps". There is a drop down that says "The Microsoft Store Only Recommended", but it is read-only and I can't change it.I did a web search for

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Windows 10 Tweaks

As you may already know, Windows 10 (as well as Windows 8) allow you to log in with a valid Microsoft account, instead of creating a local account that only works on your machine. However, you may prefer to keep a local account for privacy reasons. If you do, though, some Windows 10 features—like Cortana—may not work. Despite the default behavior, the Windows 10 Store is not one of them. You can still log in to your Microsoft account for just the Store without switching to a full Microsoft account. The process, however, is not terribly obvious. To do so, follow these steps:

• Launch the Store from your Start menu.
• Click the user icon next to the search box.
• Click “Sign-in” from the menu that appears.
• Choose “Microsoft account” and log in like normal.
• When the “Make it yours” box appears do not enter your password. Instead, click “Sign in to just this app instead.”

Start Menu Apps are Grayed-out

Many of the apps and folders in my Windows 10 Start Menu appear "grayed-out" and I don't know why (see screenshot below).





Some of the apps are from the Windows Store. When I open them, I sometimes (but not always) get an error message that says the app can't open (pictured below). Reinstalling the app from the Store usually fixes this issue. But this only happens with some of the Windows Store apps. Sometimes, they are grayed-out and they open just fine.





Not all of the grayed-out apps are Windows Store apps. Some are just regular Windows programs (for example, "Access 2016" in the screenshot above). Also, some of the folders are grayed-out too (for example, "7-Zip" in the screenshot above). I can still click on them and launch them if they are grayed-out. They are just colored gray instead of the usual white.

The items that it chooses to gray-out seem to change randomly throughout the day. Everything is fine when I first turn on the computer, but they quickly start turning gray as the day goes by.

I've tried the solutions here and here, but they didn't work for me. Most of the sites I've visited seem to be focused on fixing the Windows Store apps in particular, and don't address the broader issue of random items being grayed out.

Some sites suggested doing a Windows reinstall, but that seems like overkill (and it may not solve the root cause).

I tried updating my video card drivers, but that had no effect.

My computer is only a few months old and came with Windows 10 pre-installed.

I'm running Windows 10 Pro version 1703 (OS Build 15063.540)
